The cutting arm can rotate around its hinge point with the connecting plate 14. The other end of the cutting arm penetrates through the U-shaped frame 15. The U-shaped frame 15 can place the cutting arm to make the cutting arm horizontally placed. A cutting motor 19 is connected to one side of the cutting arm away from the connecting plate 14 through a connecting rod 18. The output end of the cutting motor 19 is arranged outward and connected with a saw blade 20. The saw blade 20 is arranged vertically. An arc-shaped protection plate 21 is fixedly arranged on the connecting rod 18. The arc-shaped protection plate covers the upper part of the saw blade 20. The arc-shaped protection plate 21 is welded and fixed on the connecting rod 18. A motor protection plate 34 is fixedly arranged at the bottom of the cutting motor 19. The motor protection plate 34 is an inverted semi-circular protection plate. When the motor 7 touches the grape branches, the motor protection plate 34 can lift the motor 7 through the radian of the protection plate to prevent the motor 7 from being entangled by the grape vines and affecting the movement of the device.

[0037] Preferably, the cutting arm includes an electric push rod 16 and a telescopic rod 17. The telescopic rod 17 is telescopically arranged in the electric push rod 16. The electric push rod 16 is hinged to the connecting plate 14. The telescopic rod 17 is vertically connected with the connecting rod 18. By adjusting the telescopic length of the telescopic rod 17, the distance between the two groups of saw blades 20 on the first cutting assembly and the second cutting assembly can be adjusted, and the width range of cutting the grape vines can be adjusted.

[0038] Preferably, a placement plate 22 is fixedly connected to the front wheel frame 4. The placement plate 22 is arranged towards the cutting plate frame 13. The placement plate 22 is perpendicularly welded and fixed to the front wheel frame 4. A jacking device is arranged on the placement plate 22.

One end of the movable rod 25 is hinged to the mounting frame 24, and the other end is hinged to a lifting frame 26. The lifting frame 26 is connected to the cutting arms of the first cutting member and the second cutting member respectively. The bottom end of the hydraulic jack rod 23 is fixedly arranged on the placement plate 22, and the top of the telescopic end of the hydraulic jack rod 23 is hinged to the middle of the movable rod 25. The lifting frame 26 is a U-shaped rod. When the hydraulic jack rod 23 jacks up, it drives the movable rod 25 to lift. The movable rod 25 drives the lifting frame 26 to lift. The two bottom sides of the U-shaped lifting frame 26 are respectively placed under the electric push rods 16 of the first cutting assembly and the second cutting assembly, so as to lift the two electric push rods 16 and make the electric push rods 16 retract obliquely upward.

[0039] Preferably, an indicator light 27, an operation panel 28, a front obstacle avoidance sensor 29, and a rear obstacle avoidance sensor 35 are arranged on the control box 2. The front obstacle avoidance sensor 29 is arranged on the top of the control box 2 and faces the front side. The indicator light 27, the operation panel 28, and the rear obstacle avoidance sensor 35 are arranged on the back side of the control box 2. The operation panel 28 is electrically connected to the indicator light 27, the front obstacle avoidance sensor 29, and the rear obstacle avoidance sensor 35. When the front obstacle avoidance sensor 29 detects an obstacle ahead, it will transmit to the controller in the control box 2, so that the controller issues a braking signal to the motor 7. When the device retreats, when the rear obstacle avoidance sensor 35 detects an obstacle, it will transmit the signal to the control box 2, so that the controller issues a braking signal to the motor 7. When the device moves forward, retreats, cuts, and charges, the corresponding lights on the indicator light 27 will light up. When the battery power of the device is low, the alarm emits an alarm sound. At the same time, the trimming operation stops, and the device stops on the cutting track 1. At this time, it is necessary to manually control the forward or backward switch of the machine through the operation panel 28, so that the device automatically returns to the charging position and stops automatically for charging.

[0040] Preferably, both the fixed wheel 5 and the adjusting wheel 6 are H-shaped track wheels. An anti-slip rubber ring 11 is sleeved on the groove part of the fixed wheel 5 on the front wheel frame 4. The anti-slip rubber ring 11 can increase the friction between the fixed wheel 5 on the front wheel frame 4 and the cutting track 1, and avoid the fixed wheel 5 from slipping when going uphill or downhill.

[0041] According to the arrangement of grape cultivation in the pergola, a cutting track 1 is erected along the grape pruning route, and the equipment is mounted on the cutting track 1. When the motor 7 is started, the equipment can move uniformly on the cutting track 1 driven by the fixed wheels 5 on the front wheel frame 4. At the same time, the cutting motor 19 is started, the extended distance of the telescopic rod 17 is adjusted, the pruning range of the grapevine is determined, and the pruning operation of the grapevine is carried out. For the sections that do not need to be pruned, the hydraulic ejector rod 23 is controlled to obliquely retract the first cutting rod assembly and the second cutting assembly upward to avoid their contact with the grapevine and affect the movement of the equipment. Signals can also be sent to the controller in the control box 2 through the remote control to realize all pruning operations such as walking and stopping on the cutting track 1, working and stopping of the pruning machine, extension and retraction of the telescopic rod 17, and on and off of the main power supply. To avoid misoperation, other protection functions cannot be remotely controlled. For example, when the battery power is insufficient, manual operation is required to control the pruning machine to move forward or backward to the starting position of the track for charging. The mechanization and automation of pergola grapevine pruning are realized.

[0042] The above only elaborates on the preferred embodiments of the present invention in detail. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention, and all such changes should be included within the protection scope of the present invention.
